Switching to PFD Mode

Simulation mode is the Aspen Plus default mode that you use to

model a process or perform calculations. PFD mode is used to

create a graphical representation of your process for a report or for

display purposes. Use PFD mode to do the following:

• Add equipment icons and streams that were not explicitly

included in the simulation.

• Display stream data.

• Display a results table.

• Add a title.

To toggle between Simulation Mode and PFD Mode, use either of

the following methods:

• Select View | PFD Mode.

• Press F12.

The check mark next to PFD Mode in the View menu and the

status bar at the bottom of the main window indicate that PFD

mode is on. Also, the process flowsheet workspace has a thick

colored border when you are using PFD mode.

When you select PFD mode, Aspen Plus creates a new graphic

identical to the original flowsheet. This new graphic is independent

of the original. Making changes to streams and blocks in either one

and toggling modes will show that these changes do not cross over.

Note: If you change the original process flowsheet model and you

wish to start over again with a new PFD style drawing that contains

these changes, select View | Reset PFD while in PFD mode. Your

old PFD will be deleted and it will be replaced by a new drawing

identical to the process flowsheet from your revised simulation

model.
